A mans mustache trimmer works great. At a retreat last year I kept hearing this "buzzzz" sound from across the room and finally had to go see what was happening. The lady was using the mustache trimmer to unsew. Stopped at Walgreen on the way home and bought one. Came home and said to my hubby, "see what I bought for you". "HUH!! I don't have a mustache". "Oh, guess I will have to use it to rip seams". Hee hee. It does work like a charm though.
